my prestashop 1.6 website is consuming to much bandwidth of my server. I track down the problem and it looks like it is the back office that is causing it. how can i fix this? do i have to disable any module?
This depends on a whole lot of things. First off, how much bandwidth is it taking? Do you have a quota? With PrestaShop, combinations can sometimes take up a lot of resources. Do you have many combinations? Another option is that it is coming from third party modules.
On your server, open the /config/defines.inc.php file. Find this line (around line 43): define('_PS_DEBUG_PROFILING_', false); In this line, change "false" to "true". Save your changes.
Now load any page of your store, either front-end or back-end, and it will display statistics at the bottom of the page. That should tell you where your server resources are allotted
